When a fine screen is placed normal to vertically the axis of the jet, examined of the concerned with the self-sustained oscillation in a shear layer. Screens with several mesh sizes are employed. The screen is moved in the direction of the jet axis. The shear layer starts to oscillate periodically and simultaneously the characteristic of the self-sustained oscillation is examined from sound radiation in the screen vicinity. Flow visualization data suggest qualitatively the shear layer-screen interaction pattern and associated after passing through the screen.
